The volume of HCl gas required to prepare the solution is 101.54 L
<h3>How to determine the mole of HCl </h3>
- Volume of solution = 1.25 L
- Molarity = 3.20 M
- Mole of HCl =?
Mole = Molarity x Volume
Mole of HCl = 3.2 × 1.25
Mole of HCl = 4 moles
<h3>How to determine the volume of HCl </h3>
- Number of mole (n) = 4 moles
- Temperature (T) = 30 °C = 30 + 273 = 303 K
- Pressure (P) = 745 torr = 745 / 760 = 0.98 atm
- Gas constant (R) = 0.0821 atm.L/Kmol
Using the ideal gas equation, the volume of the HCl gas can be obtained as follow:
PV = nRT
Divide both side by P
V = nRT / P
V = (4 × 0.0821 × 303) / 0.98
V = 101.54 L

The statement that is true of simon as an individual is; C: His annual deductible will be $800.
<h3>What is In-network Insurance?</h3>
For in - network insurance, we know the following facts;
- Charged a lower copayment rate after deductible.
- Incur a relatively low out-of-pocket amount.
- Have a relatively low annual deductible.
Now, in-network physicians help to reduce the cost of insurance to the individual and as a result, what is most likely going to happen is that Simon will have an annual deductible of $800 and is less likely that he will not pay anything after meeting this annual deductible.
The missing options are;
a. The cost of his annual physical will be 50% after deductible
b. The maximum amount that he can expect to pay out-of-pocket is $6,000.
c. His annual deductible will be $800.
d. Once he hits his annual deductible of $800, he will incur no additional costs for health care services for the rest of the calendar year.

C because the points are deducted for skipped
Given that the manager wants to know the type of vegetarian dishes that the people prefer, the sample that is going to provide him with the most accurate data is:
- a random group of 40 people on the street
The reason for this is because this sample has the most number and the people that are used for the sampling were chosen randomly.
A random sampling is very good because it provides an opportunity for every member of a population to be selected.

Answer:
The first of the basic laws of geometric optics is the law of rectilinear propagation of light. It reads: in an optically homogeneous medium the ray of light propagates in a direction.
